Valleywag Hotties puts sixteen Valley moguls and up-and-comers head-to-head in a single elimination tourney. So fill out your brackets and get ready to vote for the ultimate man of the Valley — and remember, beauty fades, but a 400-foot yacht lasts forever.

Photos of the hotties are, of course, upcoming.
